Todays samples of using heat-sdk
^{We'll be focusing on further completion of heat-sdk for now.}

This is still impressive of what they have been working on, this should be the topic not some angry trolls.

[GTTIGER]

Hmm, buying after an extreme amount of fud. How unexpected. It's almost like someone wants heat low so that they can have more.

The point is if every second post comes from the same person it isnt a warning or an opinion or criticism anymore. Its just fucking spam

Yes, no need to pay _ANY_ attention to the crap posted by some parties(party) here. Even the smallest, faintest idea of criticism has turned into delusional creating of spam.

I see a nice little gain of momentum happening. Interest gathering around the project and many things on the verge of happening.

And then they disappear when the coin reaches it's true value and beyond, its basic fudding but they always disappear once the project starts to show success

Can an updated guide be written for setting up a VPS for heatnode?

I know it's essentially the same but adding a leasing guide would help.

[jaxx88]

I also need a bit of help with the guide.
Took a ARM64-2GB from scaleway and did everything.

Chronicle procedures may need 4GB but I'm not really the expert on that. Dennis will comment when he's back at office during the next days.

Is there a way to sign a lease TX offline indefinitely (offline computer) the somehow broadcasting that instead of specifying amounts of blocks? If i need to, what is the max block number?

Max is 300,000 blocks. But after one block you can issue a next lease which can again be 300,000 blocks and starts the moment the first lease ends.
With heat-sdk you can create the lease transaction offline, sign it and broadcast it. (but this is through code, just a few lines of javascript, that you could run locally in your browser)
Through heat wallet you can do the same by opening the Lease Balance dialog.

Can you give me the steps to do this?

Is this an expected response when I start forging, from the API?
{"deadline":0,"hitTime":0}

Also, desktop wallet says "Unknown virtual account"

Forging isn't turned on in that case, indicating a problem. When it works properly you get a deadline and hittime other than 0.

Any indication on where should I start to look for issues? Or a known side effect of [insert-reason-here]? Nothing popped into my eyes from the verbose logging of the server into the wallet application

Hi, just to make sure, you do have the 64-bit java jdk installed? http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

And also the newest release? https://github.com/Heat-Ledger-Ltd/heatledger/releases/tag/v2.0.0

If running on Windows the java environment setup is crucial. https://stackoverflow.com/questions/1672281/environment-variables-for-java-installation

[jaxx88]

For windows I installed JRE 64 bit and am pretty sure that stuff works fine. The only issue for the windows environment is mining/forging. Here I used the wallet+server release.

For the hosted linux environment stuff is still unclear. In this environment I used the server release + JDK specified in the installation steps (pdf).

One thing I observed is that server release uses the new API as per configuration and for the wallet+server in windows, legacy API is enabled.

Are the coins in your account mature? They need 1440 transactions before mining/forging can be executed. And what comes to Java, I've only heard of the jdk to work.

[jaxx88]

Can you expand on coins maturing?

What coins? HEAT, BTC or others?
I have 0 coins of anything in the HEAT wallet.
Is there a prerequisite I'm missing?

Well there's your problem, you can't just get anything from nothing.

You need some Heat to forge, I think it is 1000 HEAT.

You can't just turn on the oven in your kitchen and expect a pizza to magically pop out in 20 minutes.

Yes, as LemonAndFriesOne already addressed the issue... HEAT is a Proof of Stake concept at the moment (later also PoP), so you need to invest in some HEAT before you can stake them. The monthly ROI is about 4,4% at the moment.

Q4 has been waited for forever. Hard fork and upcoming features will rock the moon out of this project.
